## Description

AUTOOL SDT103 Automotive Leak Detector for Smoke Machine, Vacuum Smoke Leak Diagnostic Tester, Fuel Pipe Leak Detector Compatible with Vehicles : desertcart.ae: Electronics

## Features

- 【Why You Need It】For example: 1. A vacuum hose leak will cause the mixture to become too thick, the idle speed will increase, the hot car will not start well, the engine will surge during acceleration, fuel consumption will increase significantly, and the exhaust pipe will emit black smoke. 2. Locking will cause idle speed to deviate and idling speed is easy to stop. 3. Air leakage in the vacuum tube will make the motor run weakly.
- 【No Air Pump】Please note: SDT103 does not have AUTOOL internal air pump External air supply is required for use Connect the shop air supply, connect the 12 V vehicle power, introduce the shop air to the AUTOOL SDT101 fuel leak tester, turn the flow dial counter-clockwise to open the airflow, switch on AUTOOL power at the back of the unit, then an SDT101 automotive smoke machine will begin AUTOOL generate smoke.
- 【External Flow Meter】You can easily control the air pressure, because the air pressure of each tube in the car is different If the air pressure is too high, the pipe will be damaged, and if the air pressure is too low, the leakage will not be detected Therefore, the flow meter is very important to protect your detection system more effectively Make testing safer.
- 【EVAP Detection】American cars that started production in 1996 are equipped with EVAP service ports; in most American cars, the EVAP service port is usually located in the engine compartment, but the EVAP service port of some special models may be located in other places. Open the plastic cover of the EVAP service port, then use the coil wrench to remove the check valve clockwise, then install the EVAP service port adapter and introduce port smoke into the EVAP leak detection system.
- 【Wide Test Range】The smoke leak detector can do smoke tests of various systems, such as EVAP systems, intake systems, refrigeration/EGR/exhaust systems, sump systems, engine airtight, vacuum leaks, low-pressure turbo leaks Cars, Motorcycles, Snowmobiles, Off-Road Vehicles, ATVs, Light Trucks and Fast Boats.
